- Quoine had originally reversed seven of B2C2’s trade on April 2017 after discovering an abnormality.
- The Singapore International Commercial Court (SICC) found Quoine liable after B2C2 sued them for the reversal.
Quoine Exchange was found liable by the Singapore International Commercial Court (SICC) for reversing seven trades, worth 3.092 Bitcoins, made by crypto market maker B2C2 two years ago. According to SICC, B2C2 sold ether (ETH) at an exchange rate of 10 BTC per token on April 19, 2017. This was approximately 250 times higher than the market rate of about 0.04 BTC to 1 ETH at the time of the trade. Quoine discovered this abnormality the next day and reversed the trade.
In August 2017, B2C2 sued Quoine, aiming to recover the 3,092 BTC from the exchange. According to B2C2, Quoine “had no contractual right unilaterally to cancel the trades once the orders had been effected.” The court sided with B2C2 in the ruling but said Quoine didn’t need to transfer back the 3,092 BTC as 1 BTC was worth around $1,300 during the time of the original trade and is presently priced at around $3,900. The court said, “Instead, the plaintiff’s [B2C2] remedy lay only in damages which, if not agreed, will be assessed at a subsequent hearing.”
Quoine said that they were disappointed with the ruling. CEO Mike Kayamori said: "We are reviewing the judgement and considering our options, including the possibility of an appeal."
